By the end you can
Use the word and balanced symbol equations for photosynthesis and respiration Calculate rates of photosynthesis and use the inverse square law (Higher) Read limiting factor graphs and say what limits the rate Compare aerobic and anaerobic respiration in muscles and yeast Work with exercise data: means, ranges, percentage increases and cardiac output Describe metabolism and measure respiration rate with a respirometer Read lactic acid and oxygen uptake graphs and calculate an oxygen debt (Higher) Calculate photosynthesis rates from graphs and timings, and predict rates and distances with the inverse square law (Higher) Revision notes
